随着汽车的普及，自行车作为一种交通工具已备受冷落。在“六五”世界环境日来临之际，某市向市民发出了一份倡议书，呼吁广大市民骑自行车上下班（Ride to Work Day）。请你就此举措用英语写一篇l20一l50词的短文，发表在某英语报上。内容要点要包括骑自行车上下班的好处，如节能环保、有利健康、缓解交通压力、易找停车位、不受堵车影响等等。

It is reported that a certain city has advocated“Ride to Work Day”recently．Personally I think We should be in favor of it．
Everyone knows that air pollution is mostly caused by waste gases produced by cars． However the number of private cars still goes up，which worsens global warming．So I’m strongly against owning and driving private cars
As a matter of fact，we can benefit a lot from bicycle riding．First, it can save a large amount of energy，which helps protect the environment．Second, riding a bicycle．every day can build up our bodies．In addition．it call relieve traffic pressure and in the meantime it’s easier for us to find places for our bikes．Actually．in big cities riding a bicycle can be faster than driving, a car because it call be free from traffic jams．
